You are generally allowed to take the following types of bicycle on the train:

• A standard, single-seater bicycle with two wheels. The bicycle must be placed in the available bicycle racks. The bicycle racks can generally fit tyres with a width of 40 to 60 mm.
• A bicycle with pedal assistance from an electric motor up to 25 km/h (also called pedelecs, up to 250 watts motor power).
• A fat bike, if it fits into the bicycle mount (usually fits tyres with a width of 40 to 60 mm). Deflate the tyres if necessary. Don't forget the equipment for re-inflating the tyres later.
• A folded folding bike or children's bikes with a wheel diameter of up to 40 cm can be stored on the train as luggage. You can use luggage racks and multi-purpose areas to store them.
• You can only take a tandem, recumbent bike or tricycle on trains with a larger storage capacity. For more information, please contact the DB Travel Centre, the DB agency or call +49 30 2970.

You cannot take any models not mentioned above. This also includes bicycles that cannot be stowed safely due to their dimensions or design. You are not allowed to take bicycles that protrude into passageways and escape routes.
